This invention relates to a combination calculating machine and cash drawer of the type in which a small calculating machine is combined with a cash drawer to form a unit that is useful for a wide variety of purposes.

The object of the invention is to provide a greatly improved combination of the character mentioned, especially one having improved cash drawer controls for adapting the unit to a wide variety of uses.

The more particular objects of the invention will appear in the following specification and drawings.

An embodiment of the invention is shown in the accompanying drawings, in which:

The calculating machine The calculating machine illustrated is of a type on the market known as the Burroughs Portable. An understanding of its details is not necessary for an understanding of the present invention and the description of the machine will consequently be confined to a general outline.

Referring to Fig. 1, the machine is provided with plurality of depressible amount keys IE) on which items may be entered. When the machine is operated, these amount keys control the differential positions to which actuator racks H (Fig. 2) move that control type bars l2 adapted to print on a piece of paper 13 on the platen M of the paper carriage l5 of the machine.

The machine is actuated by a main drive shaft [6 which may be either hand or motor driven, preferably the latter. The machine is operated 5 by first giving it a forward stroke which rocks the shaft [6 counterclockwise from its Fig. 1 position after which it is given a return stroke in the opposite direction which returns it to its original position. Connected to the main drive shaft I6 is a plate I! to which is connected a rearwardly extending link 18 that, in turn, is connected to the arm IQ of a pivoted member 20 that operates certain portions of the machine and is connected to the dash pot (not shown). It is to be observed that, at every operation of the machine, the link l8 moves rearward and is then returned forward.

The machine is provided with a register or registers (Figure 2) for receiving items and from which totals and subtotals may be taken. The controlling-arm for a register is shown as H at the rear of Fig. 1. This arm is moved and controlled by a main pitman 22 whose front end ,is forked or U-shaped. The lower fork has a hooked end 23 and the upper fork has a pawl 24 pivoted to it. The movements of the main pitman 22 are controlled by studs 25 and 26 on the plate I! connected to the main driving shaft Hi.

When the machine is conditioned for addition, 30 the parts are in the position shown in Fig. 1. During the forward stroke neither of the studs 25 or 26 causes any operation of the main driving pitman, but the stud 26 moves past the pawl 24 and behind its shoulder. At the beginning of the 3 return stroke, the stud'26" engages the shoulder on pawl. and moves the pitman 22 rearwardly which engages the register with the actuator racks. Near the end of the return stroke of the machine, the stud 25 engages the hooked end 23 4.0 of the lower branch of the pitman and returns the pitman forwardly to withdraw the register from the actuator racks.

The machine is provided with certain control keys such, for example, as a total key T, a subtotal key ST, a repeat key R; and an error key E. The machine of the present application also has a single item key SI which will be later described.

When the total key T (Fig. l) is depressed, a lever 39 pivoted'at 3! is rocked counterclockwise. This thrusts a link- 32 downward which swings a pawl 33 pivoted on the lower branch of the main pitman 22 into the path of the stud 25. Downward movement of the lever 30 also moves downward a member 34 pivotedon the main pitman 22. The outer end of this member is hook shaped and, near the center, it has a projection for disabling the pawl 24. Depression of the total key thus renders the pawl 33 active and disables the pawl 24.

At the beginning of the forward stroke with the total key depressed, the stud 25 engages the end of pawl 33 and moves the main pitman 22 rearwardly which engages the register with the actuator racks. Near the end of the forward stroke the stud 23 engages the hooked end of member 34 and pulls the pitman 22 forward again thus moving the register out of engagement with the actuator racks. During the return stroke neither of the studs 25 or 26 acts on the pitman as pawl 24 is disabled and the stud 25 does not engage hooked end 23 of pitman 22 because the pitman is already forward.

When a subtotal is taken, depression of the subtotal key ST rocks a lever 35 downwardly which moves the link 32 downward to render the pawl 33 active, but depression of the subtotal key does not move the member 34 downward and hence the pawl 23 is not disabled. The result is that, at the beginning of the forward stroke of the machine in subtotaling, the register is rocked into engagement with the actuator rack but it is not pulled out of engagement at the end of the forward stroke as it is in total taking. In fact, it is not pulled out of engagement until near the end of the return stroke when the stud 25 engages the hooked end 23 of the lower branch of the pitman.

Cash drawer The cash drawer is mounted in a housing 43 having a top M provided with a relatively large substantiallyrectangularopening. Crossbracestfi, of which one is shown in Figs. 1 andZextendacross this opening, one at the front and one at the rear, and, resting on these cross braces, is the base pan 33 of the calculating machine, the machine being attached to the pan. The top ii of the housing 46 is bent upward'around the edges of the opening in it to form an upstanding flange 33 which extends upward around the sides and ends.

of the opening. The base pan :33 of the machine has an upwardly extending flange '35 on its sides and ends, and when the pan is in position the flange 35 engages against the inner side of the flange 43. It will be noted that flange M is slightly shorter than flange 35. Mounted on the top edge of the flange 45 is a sound deadening strip 46 and fitting over this strip is the shouldered lower portion ll of the casing 38 of the cal culating machine. The shoulder of the casing rests on the strip 36 and extends downward on the outside of flange 44. The base pan of the calculating machine thus forms the top of the cash drawer housing as well as a pan and support for the machine. The calculating machine casing merges with the housing 43-3l in a neat manner with the casing outside of flange it to enable the structure to shed water and dirt. The sound deadening strip 47 serves to deaden the noise of the calculating machine that might otherwise be caused by its being mounted on top of the hollow housing containing the cash drawer.

The cash drawer 53 is preferably constructed of metal and it is mounted in the housing 13 so as to be movable from the closed position of Fig. l

to an open position and vice versa. For this purpose it is mounted upon rollers 51 of which one is shown at the left'end of Fig. '1. The drawer is urged outward by a spring 52 (Fig. 1) but is nor- .mally restrained from moving ,by a latch 53;

The latch 53 is fixed to a shaft 54 (Fig. 3) journaled in brackets on the rear cross brace 42. The shaft 54 is urged in a clockwise direction as shown in Fig. 3 by a spring 55 connected at one end to a stationary stud and at its other end to the arm 51 5 of a yoke 56 fixed to the shaft 54.

When the drawer is closed, the latch 53 normally occupies the position shown in Figs. 2 and 3 where the shoulder of thelatch is positioned in a notch 58 in a member 59 on the cash drawer. 10

The latch thus restrains the cash drawer against forward movement but the drawer may be released by rocking the latch counterclockwise a short distance.

Automatic control of cash drawer in total taking Combination machines of the character described are used in small businesses where a plurality of items are to be ,entered on the machine, printed and registered, a total taken and 20 printed, and the customer handed a slip showing the amount of each item and the total. Also, when the total is taken, the cash drawer should be opened so that the proprietor or clerk can put the cash in the drawer and make change. 25

When operations are being started, it is sometimes desirable to make sure that the machine is clear. This is done by depressing the total key and taking a total. If the machine isclear,

a special character will be printed without any 30 figures or digits. If it is not clear, the amount in the register will be printed. It is not desirable to have the cash drawer open during this totaling operation if the register is clear. Provision has accordingly been made to automati- 35 cally open the cash drawer when the. machine is operated to take a total, with which is combined the feature that, if the register is clear, the total taking operation will not release the drawer.

Viewed from another angle the latter feature is 40 combined with the above as will be later de- 3* scribed.

Referring to Fig. 2, a releasing pin 60 is mounted in the pan 43, the pin beingurged upward by aspring 6!. The pin is positioned so that its lower end is normally over an irregular 5 shaped member 62 (Fig. 3) pivoted at as to a broad plate-like extension of the yoke 56. The member 62 is urged counterclockwise, as viewed in Fig. 3, by a spring 33, the member being limited in its movementby the engagement of a projection 67 on it with a lateral lug 63 on a locking link 69 that will be later described. The outer end of member 62 rests on top of the platelike extension of yoke 56 so that when the releasing pin 6| engages the member 62 and moves it downward the extension 65 will be rocked downward and the yoke 53 rocked to release the latch 53.

The releasing pin 63 is automatically depressed at the appropriate time by the clockwise rocking action of a yoke 10 (which will be called the releasing yoke) pivoted at H and provide with an arm 12 positioned over the upper end of the pin 63. The yoke has another irregular shaped 70 arm ?3 carrying a pivoted pawl 14 on its upper end, the pawl being urged'counterclockwise by a spring F5 but being normally limited by engagement with a stud '16 (Fig. 2) on one arm' T! of a yoke '18 pivoted at E9, the other arm of 7 5 the yoke being limited against a stationary stud BI on one of the side plates of the machine.

The releasing yoke 'ifiwhich depresses the releasing pin as is controlled and actuated as follows:

Referring to Fig. l, a lever 82 is pivoted near its center to one of the side plates of the machine and urged clockwise by a spring The forward end of this lever is positioned under a lug 84 on the link 32 which, as will be recalled, is moved downwardly upon depression of either the total or the subtotal key. The rear end of the lever 82 carries a stud 85 (Fig. 2) positioned in an inclined slot 86 in the upper end of one arm 81 of a pivoted yoke 88. The other arm 89 of this yoke carries a stud 98 positioned to engage one arm 9| of a pivoted yoke 92. The other arm 93 of the yoke 92 carries a stud 94 positioned under the end of a long pawl 95 pivoted at 95 and urged clockwise by spring 91. The pivot 96 of the pawl s is carried by a downwardly extending portion 98 of one of the side arms of a bail 99 having another side arm H30, both of the side arms being pivoted losely on a shaft IOI which carries the printing hammers I02 of the printing mechanism of the calculating machine. The bail 99 extends across behind all the printing hammers and is urged clockwise by a spring Hi3.

When either the total or the subtotal key is depressed, the link 32 is thrust downwardly which rocks the lever 82 counterclockwise. The stud 85 moves upward in the inclined slot 86 and rocks the yoke 88 counterclockwise. This, in turn, rocks the yoke 92 clockwise and the stud 94 raises the rear end of pawl 95 until its end comes in front of a projection ltd on the arm 80 of pivoted yoke 18. Near the end of the forward stroke of the machine, the printing has mers 5E2 are rocked counterclockwise, when there is an amount in the register, from the position of Fig. 2 and then released to drive the type bars to printing position. As the hammers move counterclockwise they engage the bail 99 and rock it counterclockwise which thrusts the pawl 95 to the right as viewed in Fig. 2. The end of the pawl engages the projection I06 and rocks the yoke l8 counterclockwise whereupon the stud it on the arm ll of yoke rocks the pawl M clockwise from the position of Fig. 2. This movement of the pawl 14 positions its nose I55 in the path of the end of the link I8 that moves rearwardly during the forward stroke of the machine. The

arts are timed so that the pawl I4 moves to the position above explained prior to the time that the link i8 reaches the end of its movement. The link th n contacts'the pawl and the pawl, being limited against pivotal movement on arm 13 by the engagement of a projection I96 on the pawl with an offset lug IIl'l on the arm l3, moves the arm '53 with its yoke ID and depresses the pin 6! to release the cash drawer automatically.

It will thus be seen that depression of the total or subtotal keys conditions certain parts which, in turn, are further conditioned by the printing mechanism so that operation of the machine automatically opens the cash drawer near the end of the forward stroke of the calculating machine.

As previously mentioned it is not desirable to open the cash drawer when the register is clear and provision is made for automatically preventing such opening as follows:

The printing mechanism of the calculating machine described is provided with a special character printing portion which prints characters 'to indicate the operation of the machine that has just been performed. The special character printing portion of the mechanism includes a special type bar and a printing hammer similar to the rest of the printing mechanism but located on the right side of the other hammers, viewing the machine from the front. When a total is taken, this special type bar is positioned to print a certain character and its hammer is operated in the usual manner. When the register is clear, if a total is taken, none of the hammers that control type bars that print digits, are operated but the special character hammer is operated to print the special character indicating that the machine has been operated to take a total.

Referring to Fig. 2, it will be observed that the hammer for the special character type bar is cut away at lid so that when it moves rearwardly, it will not engage the bail 99. Consequently, when only the special character printing mechanism is operated, the bail 99 is not rocked and the pawl 95 is not thrust rearwardly. Accordingly, the pawl 14 on the releasing yoke is not positioned in the path of the link I8 and the cash drawer will not be released.

Single item key It frequently happens that a clerk sells only one item in which event it is not really necessary to take a total because the item is printed at the time it is entered and, there being no other items, there is no occasion for a total. If the cash drawer could not be released except by taka total as above described, it would be necessary for the clerk to go through the extra opera.- tion of depressing the total key and operating the machine before the cash drawer would open. This is an extra operation that is not desirable when only a single item has been sold. Accordingly, provision is made to automatically release the cash drawer by the depression of a special single item key.

Positioned under the stem of the single item key SI (Fig. l) is a lateral lug on a lever I28 pivoted at its forward end on a side frame of the machine. The rear end of this lever carries a stud l2! engaging in a slot in the end of the lever pivoted on the shaft 3 I. The rear end of this lever has a downward projection I23 positioned in front of a stud I24 (Fig. 2) on the pawl I4.

When the single item key is depressed the lever I26 is rocked clockwise, which rocks the lever 22 counterclockwise. The downwardly projecting rear end I23 of lever I22 engages the stud i2 5 on pawl I4 and rocks the pawl clockwise to position its nose 85 in the path of the link i8. Accordingly, when the machine is operated with the single item key depressed, the pawl M will be in the path of the link I8 and the cash drawer will be automatically released.

If desired, the single item key also functions as a non-add key in which event when machine is operated after depression of the then non-add key, the cash drawer will be automatically opened and the item will not be entered in the register but will be printed. For this purpose the lever I2l3, which is rocked clockwise by depression of the single item key, is provided With a downwardly extending portion (Fig. l)

positioned to engage a stud on the pawl to disable said pawl when the single item key is depressed. Disablement of this pawl prevents the registers from being rocked into engagement with the actuator racks and thus non-adds the machine. When it is desired to have themachine add at the time the single item key is depressed, the projection on the lever lZB is omitted, or the connections between this projection and the pawl E i are eliminated, so that the pawl 2d is not disabled upon depression of the single item key.

Locking device the drawer automatically without operating the machine. This locking device is preferably key 7 operated although it may be otherwise controlled if desired.

The locking device is mounted in the side of the housing 4B and comprises three pivoted tumblers I36, Hi, and l32 (Fig. 3) having notches H3 in their outer ends adapted to engage over a lateral lug l3-i on the link 69 that cooperates with the latch for the cash drawer in a manner that will be presently described. The tumblers l3il, 535 and I32 are urged clockwise, as viewed in Fig. 3, by springs I35, the urge being in al counterclockwise direction in Figs. 4, 5 and .6.

. This urges the tumblers into engagement with the lateral lug I34 but they may be released by means of a flat key 536 having three projections idl l33 and 53% (Fig. '7) cooperating with complemental surfaces i3'i, I38, I39 (Fig. 4) on the tumblers. It will be understood, of course, that diiierent combinations of projections and coacting surfaces can be used to get different locking combinations and that a difierent number of tumblers can be employed if desired. It will be noted, however, that the key is a flat key and that its projections can be turned to raise the tumblers to released position after which they pass the surfaces on the tumblers and allow the tumblers to drop back again. The tumblers have lower notched portions MG (Figs. 4, 5, 6) for locking the lug i35 if the tumblers are raised too high by the use of a wrong key.

The key is also provided with a wide projection l ll (Fig. 7) for moving the link 69 forward and backward.

If the key B6 is inserted in the lock with the parts in normal or central position and turned clockwise from its Fig. 4 position to its Fig. po-

' sition, which would be counterclockwise in Fig.

l, the ey first turns around to a position where it releases the tumblers lliil, l3! and E32 from the lug H36 and, at about the same time that they are released, the wide projection Hi! of the key engages a shoulder M2 on a dog I43 pivoted at Hi l to the link 59 and urged counterclockwise as viewed in Fig. 4 by a spring Hi5. Further turning movement of the key moves the link 69 to the right as viewed in Fig. 4, or to the left as viewed in Fig. 1. The lateral lug i3 5 moves away from the notches I33 in the ends of the tumblers to the position shown in Fig. 5 where the tumblers drop back when released by the key and another set of notches M6 lock the link 69 in the position to which it has been moved. The link may be released by inserting the key and turning it in the opposite direction which raises the tumblers and allows link 5Q to move back to its original positionwhich it does under the influence of spring 66 (Fig. 3) which urges member 62 counterclockwise into engagement with the lug 68 on link 69. If with the parts in normal or central position, the key is inserted and turned counterclockwise as viewed in Fig. 4, or clockwise as viewed in Fig. 1, the broad projection Ml of the key moves past the dog 13 without moving link 69. But, as viewed in Fig. 6, at the time the projections on the key release the tumblers, the broad projection Ml engages the cam shaped face I53 of a projection l5l on the link 69 so that further turning of the key forces the link 69 to the left, that is, to its Fig. 6 position, which would be a movement to the right or rear in Fig. 1. The tumblers are not allowed to drop back to a position to lock the link in its new position but are held upward by the lug I34 as shown in Fig. 6.

It will thus be noted that, when the key is inserted in the lock and turned in one direction the link is moved in one direction and latched. When the key is inserted and moved in an opposite direction the link is moved in the opposite direction but is not latched.

Referring to Fig. 3, it will be observed that the rear end of the link 69 straddles the stud led on the arm 51 of yoke 56. The link also has an upstanding and laterally projecting lug 58 en-.

gaging the projection 61 on the irregularly shaped member 62 pivoted at 64 to the plate 65 on yoke 56.

When the link 69 is in its normal or central position, which is the position where the locking device is in normal condition, the parts occupy the position of Fig. 3. If the key should be inserted in the locking device and rotated to the right as viewed in Fig. 3, the link 69 will be thrust to the right and its action in pushing on stud [56 will rock the yoke 56 counterclockwise which will result in rocking the latch 53 upward to release the cash drawer. Accordingly, by a simple clockwise turn of the locking device by means of the key I36, the cash drawer may be automatically released without the necessity for a machine operation. As soon as pressure on the key is released the parts return to normal under the urge of spring 55.

On the other hand, if the key is inserted and the spring 55 However it cannot move far because of the engagement of the top of a stud iti on the member 65 with the cross frame member 42. As the link 69 moves to the left in Fig. 3, the lug 68 engages the projection 67 on the member 52 and rocks the member about its pivot 54 against the tension of spring 66. This moves the outer end of plate 62 clockwise out of the path of the releasing pin 65 with the result that the latch 53 for the cash drawer cannot be released no matter what the operation of the machine may be because depression of the pin 68 does not rock the yoke '56, there being no member directly under the pin. Accordingly, when the key 5 36 is inserted and moved counterclockwise, the cash drawer is locked and cannot be'opened by a clerk'no matter how he operates the machine. It is necessary to have a key to unlock the locking device in order to get at the cash drawer or to restore the parts to a condition such that the cash drawer can be opened by a machine operation.

Modifications If it should be desired to release the cash drawer for every operation of the machine regardless of the character of the operation, the above described machine can be quickly converted into one for accomplishing this result by substituting a yoke IIO' shown in Fig. 8 for the yoke Iii of Fig. 3. This yoke is mounted on the same pivot stud and has an arm III positioned over the release pin 60. The other arm I12 of the yoke is not provided with a passby pawl but has a curved end I'I3 positioned so that it will be engaged by the end of the link I8 upon every rearward movement of said link. Accordingly, upon every operation of the machine the cash drawer will be released.

If it should be desired to release the cash drawer upon every operation of the machine except a non-add operation, the yoke I 35 shown in Fig. 9 may be employed. This yoke is mounted on the stud II as a substitute for the yoke I0. It has an arm I8I positioned over the release pin 60. The other arm I82 of the yoke carries a pawl I83 having a stud I84 to which a spring is connected for urging the passby pawl to a position where the nose of the pawl will normally be in the path of the end of the link I8. In this form, the rear end I23 of the member I22, which is operated by depression of the non-add key, has a further ofiest portion I85 positioned under the stud I 84. When the non-add key is depressed and the member I22 rocks counterclockwise, the pawl I 83' will be rocked counterclockwise out of the path of the link I8. Accordingly, when the non-add key is depressed and the machine operated, the cash drawer will not be released but it will be released upon every operation other than an operation with the non-add key depressed.

It is to be understood that the construction shown is for purposes of illustration only and that variations may be made in it without departing from the spirit andscope of the invention as defined by the appended claims.
